Patent CA-2030710-A1 (CA)
Title: Orthopaedic support
Inventor: MCKENZIE ROBIN A
IPC: A61F5/02
Filed: 1990-11-27
Abstract: ABSTRACT            Orthopaedic supports to maintain lumbar lordosis are known and are in the form of cyclindrical rolls cut from slabs of polyurethane.  In this invention, the support is in the form of an elongate pad that is substantially D-shaped in cross-section and that has been moulded from material that has a compressibility such that a 25 percent indentation into the pad requires from about 8.8 kPA to about 10.7 kPA applied pressure.  The surface of the pad that in use engages a person's back is slightly concave along its length.  The pad has better mechanical strength than the known rolls and is more adaptable in use.

Abstract: Alkyl-isothiocyanic esters having the formula R-N=C=S can be produced by reacting N-alkyl dithiocarbaminates with hydrogen peroxide in aqueous phase at 95 to 130°C.  According to the present invention the aqueous N-alkyl dithiocarbaminate solution is reacted with a 20 to 40% by weight aqueous hydrogen peroxide solution in a volume ratio of 1:0.8 to 1 while maintaining a pH value of 1.5 to 4.5. The solutions are preferably sprayed into a reactor while alkylisothiocyanate formed is distilled off in the form of a vapour and the aqueous phase containing the by-products accumulates in the reactor.  By means of the process according to the present invention the space-time yield could be increased significantly while, as compared with the conventional process that is carried out at pH 5 to 9, the amount of sulphur formed is substantially reduced and the shut off times for cleaning the reactor can be minimized.
